Of interest to organic gardeners and eaters, England proposed refusing to accept any produce that has to be flown into the country. The organic certification organization, Soil Association, cited the fact that air planes pollute the environment as their rationale.

England and Canada are removing lawn pesticides to shelves behind the counter where purchase will require a prescription-type form.

In the United States, organic growers and milk producers are having difficulty keeping up with demand. The industry as a whole is growing. In response, the U.S. House of Representatives Agriculture Committee designated Representative Dennis Cardoza (D-CA) to chair a new subcommitteeon Horticulture and Organic Agriculture.

All bare root plants are drying out every day they sit in the boxes. Buy early. The roots can be soaked for an hour or up to overnight but you will have better luck if they have not been sitting around in a heated store for several weeks before you bring them home.

In addition to the information printed on the packages, here are links to useful OSU fact sheets

Cleaning out old emails, I found a few links of interest to those who would like a set of building plans for a small hoop greenhouse. Both provide photos, diagrams and list of materials with approximate cost to build.

A new question came in about how to build a small green house inexpensively.

A hoop house is usually recommended as a small project greenhouse. Take a look at the listings on this link at Build It Solar. Lots of possibilities there.

Also, check the library. There are several do-it-yourself books with plans for basic greenhouses.

Some long-time gardeners think that with global warming, a home gardener only needs a simple cold frame unless you have your heart set on a greenhouse. There is a set of instructions for a raised cold frame at Ron Hazleton's site. Click here to see them.

If you can't find what you want at the library or online,The Noble Foundation in Ardmore has a DVD with instructions on how to build a $500 or $600 hoop house which is the minimum they cost to construct.

If you have a greenhouse you can start seeds now but if you are planning to grow from seed in the house you will need a florescent shop light type setup that hangs a couple of inches over the seed pots. One writer suggests lining the wall behind the seedlings with mylar to intensify the light.

Renee's lavender seed package indicates that the seeds germinate at 60-to-70 degrees so they will need to be kept warm enough to get started. Or you will have to wait until the weather warms up above our current 30-degrees. You can click around Renee's site to read the packets on the others seeds they offer.

These two 60-degree days between the cold blasts have worked wonders for those of us who need sunshine for a feeling of well-being.

Yesterday, I pulled all the tiny weeds out from among the emerging poppies and daffodils in a 20-foot long bed out by the compost bins. To sit in the sun on a beautiful, warm day, rescuing tiny plants took my attention away from the ice storm damage all around.

Gardening is therapeutic in its ability to make everything else seem unimportant, no matter which plants survive Mother Nature's many and varied moods.

The disadvantage of so-called fast growing permanent, structural plants is that they tend to be weak and need to be pruned more often. Leyland cypress, frequently recommended in Oklahoma, can grow two or three feet a year. Fast growing trees like silver maple and the male pear trees, called Bradford pears split and tear in the wind (and ice!).

Consider your needs and resist selecting plants that say "fast growing" on the label. The one great use for those fast growing trees and shrubs is to plant them along side slower growing trees or shrubs such as oak or holly. The slow growers will be ready to take over about the fifth year, when the fast growers have to be removed.

If you live in the country or have taken a winter walk in the woods, you may have seen skunk cabbage coming up with its characteristic pink and white pod-like new growth. The ice and snow on the ground around the plant will have melted.

I had always thought that the melting allowed the plant to emerge, similar to a late winter or early spring bulb such as crocus. But no. The plant actually is warm blooded. Skunk cabbage provides its own warmth; its leaves and flowers cannot tolerate frost.

Wow! The photo is our garden shed after the ice storm broke the trees around it.

This summer, there were flowering vines, purple millet and flowers on the right, bird houses and flowers on the left.

The best thing to do is wait until the ice melts to assess a plan of action. Don't try to remove any tree branches unless they are blocking something like a driveway or door. Pulling on them now could cause even more damage.

I've been searching for this poem for you and found it this morning. Enjoy.

The kiss of the sun for pardonThe song of the birds for mirthOne is nearer to God's heart in the gardenThan anywhere else on earth

Even I will not try to garden this weekend as we have a few days of winter that a British friend of mine would call "proper weather".

We did fill all the bird feeders with black sunflower seed, suet and thistle. Tomorrow and as long as this freeze lasts, we will add boiling water to the birdbath so the birds have a place to get water.

Two companies have sent the seeds I ordered but I will wait another couple of weeks to start the Brussel sprouts and other cool weather plants inside. Most years, I start them so early that they become too leggy and weak before I can put them out into a cold frame.

Cover up your legs with a blanket and enjoy a good read with a cup of something hot to drink.

Houseplants suffer from the stale, dry air in our winter homes, but more than that they suffer from overwatering.

Seeing little black flying bugs in and around house plants is a sign that the plant's soil needs to dry out more between waterings. The bugs are harmless to the plants but helpful to let you know when to cut back on water.

Running a small house fan close to plants in the house can help them, too. The air circulation helps strengthen the stems. Also, when watering house plants dump out any water that remains in the saucer. If you have ferns and think they need humidity, fill a shallow pan with stones and put the pots on top of the stones. Keep the water below the level of the top of the stones.

And then there are the small, yellow mushrooms in houseplants. They are the reproductive structure of a soil fungus. Also harmless to plants but poisonous to people and animals, so just to be on the safe side, remove them and dispose of them.

I heard that the library in Ft. Smith Arkansas has a green roof though I haven't checked it out yet. On the green roof topic, this just came into my email.

The American Society of Landscape Architects Library and Education Advocacy Fund (ASLA Fund) will receive a $22,000 grant from the National Endowment for the Arts (NEA) for outreach and education programming surrounding the Society’s new green roof demonstration project.The grant will fund an exhibit, a student workbook, and a discovery program to help raise awareness of how green roofs improve air and water quality, reduce the urban heat island effect, manage stormwater run-off, replace bio-habitat, and provide esthetic amenities to tenants and neighbors and economic benefits to developers and building owners.

“One of the main reasons ASLA decided to build a green roof on our headquarters was to show people what a green roof looks like and demonstrate the many environmental and economic benefits,” said Nancy C. Somerville, executive vice president/CEO of ASLA, who also serves as president of the ASLA Fund. "Not only will this grant enhance the experience for our green roof visitors, it will enable us to reach audiences of all ages across the country and around the world who may not be able to visit our project in person.”

Red yucca's horticultural name is Hesperaloeparviflora. A garden writer wrote about it surviving at least -25F without benefit of snow cover in a friend's Minnesota garden.Like the familiar evergreen yuccas in our yards, the red variety grows to 2-3ft high, with a spread up to 4ft. The flower stalks are 4 feet or taller.The only attention my yucca requires is grooming twice a year. In particular after blooming, the faded flower stalks can look unattractive. In the winter, I remove the dead leaves at the base and usually find several baby plants under there. As for summer attention, yucca requires nothing on your part, not even water. The leaves are prickly, so plant yucca where children and pets do not play. When you need to groom the plants wear long sleeves and gloves.

Take a look at the link and see if you have a place for them in your landscape.

Earlier this year we had a chain link fence put up because the neighbor's huge dogs wanted to live in our yard.

While the crew was outside, I pulled weeds, enjoying the balmy weather. The fence company owner said his wife grew a lot of herbs and "that henbit sure is a problem the way it grows into everything."

What's henbit?

You may already know, but I started looking into weeds to find out. A gardener has to be able to recognize weeds when they emerge so we know what to pull and what to leave.

There is an old saying that you can tell a weed from a desirable plant by how difficult it is to pull: The expensive perennial will come out easily and the weed will hold on for dear life.

If you are also curious about what's what in your flower beds, Oklahoma State University provides this easy to use website that will help identify the weeds though they do not offer to help pull them out.

In the latest issue of Brooklyn Botanic Garden's online science journal, Urban Habitats, there is a special section on the use of green roofs as nature habitats for plants and birds. Researchers from Europe and the U.S. show that green roofs are effective when used for nature.

One green roof in Germany, built 90-years ago, was planted with an orchid garden in native soil. Their success led to more green roof being put in place in London over the past 15 years. Now ecologists are hoping green roofs will help solve the problems of degraded urban environments.

I ordered flower, vegetable and herb seeds today and it made me think about how many seeds have been planted too early. Instead of growing strong stems with healthy true leaves, they get tall with thin, lanky stems.

Resolve this year to learn more about each type of seed and give them what they need to be successful: Sterile pots, sterile starting soil, light source, warmth, run a fan on them to make strong stems and pick them out to reduce the number of seedlings per pot. It is New Year's Day after all and resolutions are in order.

Organic Gardening Magazine provided guidelines for a few vegetables that will serve as examples.

Broccoli seeds - 4 to 6 weeks from sowing to transplanting. Plant outside 2 weeks before last frost. Translation: Assuming our last frost to be April 15, seeds should be planted inside between Feb 15and March 1 and moved outside April 1.

Melon seeds - 3 to 4 weeks from sowing to transplanting. Plant outside 2 weeks after last frost. Translation: Last frost is April 15, plant outside May 1st. Sow indoors March 7.

Tomatoes - Plant outside May 1st. Sow seeds inside mid-March.

Succession planting works best for most families. For example, two heads of lettuce a week is enough, so plant half a dozen seeds a week for several weeks.

On the web at http://www.backyardgardener.com/tm.html there is a timetable of flower germination data. It includes planting depth, soil temperature, days to germination, type of planting medium and comments.
